Description

The Petra Side Trim Pants in Black suit a work trip, a casual office, and a weekend dinner with friends, thanks to a clean straight leg and a thin zebra line down each side. A chain charm at the waist adds a little metal. They are smart casual pants, and a formal event or a strict dress code will want something plainer.

Fabric
Cotton leads at 67%, with 30% polyester and 3% elastane. Up close you can see a diagonal twill weave, with a soft sheen on the black under studio light. This pair comes from the atelier Luna runs in Serbia.

Fit
The waistband sits at the natural waist, closed by a metal button, with loops for a belt. The model wears size 2. Straight legs reach the top of her sneakers, so flat shoes suit the length best. Set your waist and hip against Luna’s measurements to choose.

Styling
Off to the airport, tuck in the white half zip Margita, which shares the same small metal rings.
Casual Fridays can take a clean top like the ivory Mila with its red trim, and sneakers still work if your office allows them.
Belts help on longer days: thread the Wendy logo belt through the loops.

Care
Wash at 30 C (86 F) maximum. Do not bleach. Do not tumble dry. Iron on low heat. Professional dry cleaning is suitable.

Other pairs sit under all Luna pants and outfits for work, and the guide to an easy outfit formula shows how to wear them.

Are the black Petra pants business wear?
They suit a casual office and a work trip. The side piping and chain make them less formal than a tailored pant, so a client meeting calls for the Rina navy instead.
What does the zebra trim look like on the Petra black pants?
It is a thin black and white line down the side seam. You notice it at close range or when she turns, and from the front the pants look plain black.
What fabric are the Petra black pants?
The fabric is 67% cotton, 30% polyester, 3% elastane. A twill weave shows in the close photo, and no lining is listed.
Which belt fits through the loops on the Petra black pants?
A narrow belt such as the Wendy logo belt in black works with the loops. It also keeps the black running unbroken from the top of the pants down.
How do I clean the black Petra pants?
Wash at 30 C (86 F) for black Petra, and keep bleach and the tumble dryer away from them. Set the iron to low. Dry cleaning by a professional is also fine.
Do the Petra black pants need flat shoes?
They reach the top of the sneakers on the model, who is in size 2, so flat shoes suit this length. A heel will show more ankle. Your waist and hip on the chart are the place to begin.
